Two new large mooring buoys just from the South Dock Marina entrance and a new east cardinal buoy off Convoy’s Wharf, all in Limehouse Reach.

8 reduction of depth in and around the Gull Stream. It is worth noting the drying height on the western side of the Goodwins, pretty close to a lateral line from the West Goodwin SHB to the NW Goodwin cardinal buoy. Favouring the eastern side of the Gull Stream seems an obvious precaution in a SW wind!

Note 2 of the reduced depths are at the same lat/long with the same reduced depth of 8.6m, the second on the Wk mark. The image from Imrays had already been recording the depth of 8.6m so is indicated on the image as a ‘tick’.

This is a sad time when five useful marks are unmaintained and now declining. Topmarks of each of the five beacons listed have now apparently fallen. Unfortunately as the Middle Sand is a red and white beacon, this can now be regarded as a safe area once the stump has fallen below the HW.

A series of NtM has been issued over the last two weeks revising the Military and Historic Wrecks for different charts. The practice is to add the legend at the site of the wreck for each chart and the replacement of the existing note to be placed in the Chart Title area. The slight variation in the positioning of the wreck is in consequence of the Coordinate System (i.e. WGS84 or other).

This is a very slight reduction of depth in respect to the first item of NtM 213 of 2017 (Week 3). The reduction is from13.5m to 13.3 so not an issue for leisure craft.

Seven reductions of depth in the River Thames: two off Hole Haven at the northern edge of the shipping channel, one north of Mucking No 1 SHB and 4 on the southern edge of the shipping channel between the West Blyth and Cliffe Fleet PHB. Only north of the Mucking No 1 is likely to hinder leisure craft.

This is a small but important move of the starboard hand buoy ‘B2’. This is the third relevant NtM in the area and all are now included in the image below.

Work on the extension to the Kentish Flats Wind Farm has started and is expected to be completed this summer. This notice extends the limits of the wind farm to include the extension and gives notices of the three cardinal buoys placed to mark the work area – to be avoided during construction.

This is intended for shipping but will be Worthing noting for skippers who pass by the Mouse and Knob areas.

The note is revised to:

DESIGNATED ANCHORAGE AREAS

Vessels requiring to wait at anchor must do so only in the designated anchorage areas. Within these areas, mariners are requested to use the anchor berths. Vessels may not anchor in a fairway except in an emergency or for the purpose of manoeuvring. Anchor berths K3 (51030'·4N 1°04'{lE), W1 (51°3Q"9N O~55"9E) and W2 (51°31"2N 005T'1E) are reserved for vessels nominated by London VTS. For further details, see Admiralty list of Radio Signals.

This is a chart annotation resulting from the work started in 2014 to construct a rail bridge over the Upper Medway as notified in East Coast Pilot in October, 2014 (see http://www.eastcoastpilot.com/latest_news.html). The plan is to provide a 20m wide gap in the works and 5m air draft at MHWS during construction with an ultimate air draft when completed of 8m.

1. As part of the recent dredging campaign for the London Gateway Project and the deepening of channels between the Sunk (51° 51´·70N., 1° 38´·77E.) and Sea Reach (51° 29´·70N., 0° 29´·70E.), significant changes affecting deep draught vessels will occur on the 1 October 2013.

2. The following is a list of the major changes that will happen on that date (please refer to the three diagrams opposite):

a. Within the Sunk Inner Precautionary Area, the Sunk Deep Water Route will be moved approximately 250 metres to the north west so that it runs parallel to the old route. The new route will be marked by the Sunk Inner Buoy which was moved earlier in August. A new buoy is to be laid to mark the wreck of the Dynamo – see London Gateway Project, changes to

ships routeing – Figure 1.

b. In the vicinity of the Sunk Head, the Sunk Deep Water Route will lead into a new deepened channel approximately 300

metres wide and 5000 metres long. A new special marker buoy (SHM) will mark the junction of the Trinity Deep Water

Route to this new channel – see London Gateway Project, changes to ships routeing – Figure 1.

c. In the Black Deep and Fisherman’s Gat Precautionary Area, a new Deep Water Route and deepened channel will be established marked by special marker buoys – see London Gateway Project, changes to ships routeing – Figure 2.

d. In the Knock John Channel, all the buoyage is to be repositioned to mark a slightly amended 300 metres wide deepened channel – see London Gateway Project, changes to ships routeing – Figure 2.

e. In the Oaze Precautionary Area, the Deep Water Route is to be moved south of its current charted position with buoyage repositioned to mark the channel and special marker buoys inserted to mark significant wrecks – see London Gateway Project, changes to ships routeing – Figure 3.

f. The Yantlet Channel will be extended by 3000 metres east south east to link in with the Oaze Deep Water Route near the West Oaze buoy – see London Gateway Project, changes to ships routeing – Figure 3.

g. The Oaze Precautionary Area is to be extended northward by approximately 500 metres in the western part of the Warp area – see London Gateway Project, changes to ships routeing – Figure 3.

3. Mariners are advised that these measures have been put in place specifically for deep draught vessels. Where smaller vessels have sufficient sea room to navigate safely away from the Deep Water Route they are encouraged to do so.

4. For further information mariners should refer to the Port of London Authority.

5. These changes will be included on New Editions of charts 1183, 1185, 1186, 1606, 1607, 1609, 1975 and 2692 to be published in November 2013.

This notice is a Trinity House Notice at present (No 18 of 2013). This notice combines with PLA Notice to Mariners No 14 of 2013 (shown in these pages last week) and two earlier notices to illustrate all the changes that will occur this year in preparation for the commissioning of the London Gateway.

This notice from Trinity House lists the changes that will be made in October, 2013 and affects many charts.

In order to provide readers with simple, clear and useful information, CTTE is publishing a PDF providing a comprehensive list of all the changes occurring during August under the PLA notice and in October under the Trinity House notice. The PDF includes three images illustrating the buoyage as it will be once concluded in October.

The RYA have made enquiries and there is no intention to bring in any restrictions for leisure craft but of course normal Regulations will apply in the Sea Reach to Black Deep channels where large container ships will be constrained by the draught.

Now amended by PLA NtM 14 of 2013 and UKHO Notice 4255(P). PDF below was amended again on 23rd September, 2013

During August 2013 a new gated buoy layout will be placed in Yantlet Channel between Sea Reach No1 buoy (51°29´·5N., 0°52´·7E.) and Sea Reach No 7 buoy (51°30´·1N., 0°36´·4E.) (ETRS89 Datum). The centre line buoys will be removed.

Mariners are advised to refer to the Port of London Authority and London VTS for the latest information.

Charts will be updated when the buoy changes are complete.

PLA Notice

SEA REACH - ADVANCED NOTICE

NEW YANTLET CHANNEL - BUOYAGE LAYOUT

AMENDMENT TO L14 OF 2013 ISSUED ON 5TH JULY 2013

During August 2013 a new gated buoy layout will be put in place in 2 phases for the dredged and deepened Yantlet channel by Marine Services Vessel HOOKNESS. Gated buoys will be placed along the dredged channel edge in line with the pre-dredge positions of Sea Reach 1 – 7 buoys. The centre line buoys will be removed.

Phase 1

On or about 12th August 2013, Sea Reach centre line buoys 1, 3, 5 and 7 will be removed and the following gated buoys substituted. Work is expected to take 4 days to complete.

This notice confirms the temporary notice issued by the Thanet Wind Farm in the previous week with the removal of all but one of the light buoys marking the Thanet Wind Farm during construction. Thanet N and the Drill Stone remain in position.

The notice also includes two new depths in Trinity Bay and Kellett Gut (near the Goodwin Sands).

This is a late ‘catch-up’ on the buoyage changes in the Whitaker and Swallowtail channels from July, 2011. (yes, I did mean July, 2011). Chart 1183 is not one probably used by Leisure Craft being the whole Thames Estuary and it deals with the changes by deletion of the old marks and insertion of a legend saying the channel is ‘buoyed’.

I am aware that the Imray chart (2000.8, included in Imray/Meridian ID10) was correctly printed and republished in August, 2011 – DO NOT TRY TO APPLY THIS CORRECTION TO THAT CHART – although it would apply to earlier versions.

The UKHO Leisure Folio 5607.3 was republished in December, 2011 (9th Edition) and similarly will not need emendation although the 8th Edition will.
